Let's divide 84280807 by 240
We want to divide 84280807 by 240.

Going ahead to step 1:
240 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 240

On to step 2:
The number 240 fits into 84 0 times, leaving a remainder of 84.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 84 to get 84.
Fetch the next digit (2) from the dividend, attach it to 84 and continue: 842 / 240

Step 3:
842 divided by 240 is 3 with a remainder of 122.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 720 from 842 and we're left with 122.
Grab the next digit (8) from the dividend, add it to 122, then carry on: 1228 / 240

Let's proceed to step 4:
The number 240 fits into 1228 5 times, leaving a remainder of 28.
The number 5 becomes the next digit in our result. 
Result so far: 35.0
If we subtract 1200 from 1228, we get 28.
Append the next digit (0) from the dividend to 28 and continue with: 280 / 240

Step 5:
If we divide 280 by 240, we get 1 and a remainder of 40.
Write down 1 as next digit of the result. 
Result so far: 351.0
The remainder is 40 after subtracting 240 from 280.
Fetch the next digit (8) from the dividend, attach it to 40 and continue: 408 / 240

On to step 6:
408 divided by 240 is 1 with a remainder of 168.
Use 1 as the next digit of our solution. 
Result so far: 3511.0
Subtracting 240 from 408 leaves us with 168.
Take the next digit (0) from the dividend and append it to 168, then repeat: 1680 / 240

On to step 7:
1680 divided by 240 is 7 with a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 35117.0
If we take 1680 away from 1680, we end up with 0.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 240

Moving on to step 8:
240 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 351170.0
If we take 0 away from 7, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 9:
The number 240 fits into 70 0 times, leaving a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 351170.0
If we take 0 away from 70, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 10:
240 goes into 700 2 times with a remainder of 220.
Put 2 as the next digit of the answer. 
Result so far: 351170.02
If we subtract 480 from 700, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

On to step 11:
2200 divided by 240 is 9 with a remainder of 40.
Put 9 as the next digit of the answer. 
Result so far: 351170.029
If we subtract 2160 from 2200, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 12:
400 divided by 240 is 1 with a remainder of 160.
Use 1 as the next digit of our solution. 
Result so far: 351170.0291
If we take 240 away from 400, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 13:
240 can be fit into 1600 6 times, resulting in a remainder of 160.
The number 6 becomes the next digit in our result. 
Result so far: 351170.02916
Subtract 1440 from 1600 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 14:
When dividing 1600 by 240, we get 6 with a remainder of 160.
Put 6 as the next digit of the answer. 
Result so far: 351170.029166
Deduct 1440 from 1600 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

The final result is 351170.029166 with a remainder of 1.6e-05.
